ASCII art Reed–Kellogg sentence diagrams are probably hard to find anywhere, and Graphviz can't really express Reed–Kellogg diagrams. But Reed and Kellogg published their somewhat ad-hoc diagram language in 01877, 78 years before what we now call "linguistics" was known in the West thanks to Chomsky's work in 01955. These are among the reasons I thought it might be a good idea to use the form of sentence diagrams used by linguists instead of the more compact Reed–Kellogg diagrams.
